TTSOSC Review and Target Recycled Baseline Current 2004 2008 Recycled In-House Reduction in Waste to Landfill 59% 52% --- 70% 67% 32, 000 Remarks TTSOSC Roads to Recycling Report • 2, 100 tonnes waste to Murray Browns • 2, 300 tonnes to Clarkes • 300 tonnes planings utilised as Type 1 subbase Area 6 • 1, 000 tonnes Type 1 sub-base produced at Towton

TTSOSC Review and Target Recycled Projection 2009 75% Recycled In-House 71% Reduction in Waste to Landfill Remarks 5, 000 • Increase utilisation of planings as sub-base up to 5, 000 tonnes • Increase sub-contract recycling e. g. Stabilised Pavements, approximately 10, 000 m 2 planned or under construction this year Note : Data derived from BBIS “Matter Tracker” and “ERP” costing System

TTSOSC Review and Target

Gully Waste to Landfill Annual (tonnes estimate) Period Operator LFT Waste Stream No LFT All waste to landfill. 2003 / 2006 ISS Waterers 4, 000 0 2006 / 2007 ISS Waterers 800 3, 200 ISS / BBIS agreement with Yorwaste to dewater at Harewood Whin. Note significant haulage distances. 2007 / 2008 ISS / BBIS 0 4, 000 Increase in suppliers e. g. Gwilliams at Ebberston in the East. Gully Emptying brought in house to improve control of the works and improve recycling and cost reduction. 2008 / 2012 BBIS 0 4, 000 BBIS are looking to further recycle waste by its own dewatering system. This includes recovery of grey water. NYCC considering reduction in frequency of gullies emptied to improve sustainability and reduce costs.

BBIS Recycling Business Plan Objectives / Targets Progress 07/08 Zero Waste to Landfill • Landfill reduced in past two years from 69% to 32% of total amount excavated 100% Recycling • 1, 000 tonnes of recycled Type 1 and 1, 000 tonnes of single size drainage material produced at Towton in 2008 • 70, 000 m 2 of surface dressing using recycled chippings • Approximately 20, 000 t of road planings recycled either in house or with third parties Planings Used in New Surfacing • BBIS/TRL to undertake trials with “Pre-Heat Asphalt” utilising planings in 2009. Laboratory test underway with TRL at this time Commercial Advantage to NYCC Maximised • For material that we are unable to recycle, tipping charges reduced from £ 16. 02/tonne 2005/06 to £ 8. 08/tonne 2007/08 which equates to a 55% reduction in tipping charges

Re-use In order to reduce the cost of supplying new products, some materials will be taken up on site and re-used. • Stone paving slabs • Cobbles and setts • Traffic signs and posts • Drain covers • Concrete kerbs

Looking to undertake a crush in late 2009. Past programmes have identified that sub-bases will be required in the vicinity of this location. Due to limited space only hard materials to be stockpiled. Wombleton Significant quantities of materials in store which could be crushed. Past programmes have identified that sub-bases will be required in the vicinity of this location. Planning approval unsuccessful, one-off crush and screen being considered for materials stored there.

Innovations and Developments in 2008 TTSOSC - Recommendations Recommendation 1 That the Innovations Group of Highways North Yorkshire present technical reports on an annual basis to the Transport and Telecommunications Overview and Scrutiny Committee Recommendation 2 That the feasibility of utilising Incinerator Bottom Ash Aggregate (IBAA) as an aggregate for use in highway works be looked into by the County Council Recommendation 3 The Transport and Telecommunications Overview and Scrutiny Committee to monitor performance indicators specifically associated with re-use and recycling Recommendation 4 The Transport and Telecommunications Overview and Scrutiny Committee to monitor performance indicators specifically associated with re-use and recycling: % of recycled materials used in highways maintenance % of Highway waste disposal to landfill Recommendation 5 That there is a clear commitment from the County Council to maximise (subject to economic assessment) recycled content in highway works.

Innovations and Developments in 2008 TTSOSC Recommendation Development Examples 1 Technical reports to TTSOSC annually Current reports (this presentation) 1, 4, 5 Innovation reports being prepared to support sustainability Foamix, Infra Red patching trial 2 m 2 Rillington, Cement Stabilisation 9, 960 m 2, plastic (lightweight) kerbs 700 m Area 6 Dacre Banks, Scarah Bank and 800 m Area 7 Barkston Ash and A 162 South Milford. 3 Measure the recycled content of key operations and materials Matter Tracker and ERP are BBIS systems which are utilised to monitor excavations and recycled aggregates. BBIS working with supply chain to develop monitoring of products purchased. 1, 200 tonnes of Slag, 1, 000 tonnes sub-base. Increase awareness of current Design Guides and Specifications Utilisation of recycled crushed concrete as sub base and road planings as sub base. All tested and approved for re-use. h. NY partners working on an update of NYCC Construction Manual. Site Waste Management Plans (SWMP) will be utilised in the future on significant works to improve waste streams. SWMP already completed for Surface Dressing 2008/09. 4, 5

Innovations and Developments in 2008 TTSOSC Recommendation Development Examples 4, 5 Consider owning part of the supply chain to drive improvements in recycling Trial with h. NY and TRL commenced considering use of road planings in “Re Heat” asphalts 4, 5 Engage with the supply chain to support NYCC recycling initiatives W C Watts, Tarmac and Stonegrave Aggregates engaged to increase recycling and reduce costs of LFT. Reduction of further £ 3. 67/t in 2007/08. 4, 5 Set up recycling centres Towton and Blackman Plantation now operational. Skipton Rock Quarry at feasibility study stage. Monitor h. NY programme to manage materials effectively. 4, 5 Recycle Surface Dressing Chippings Untreated chippings successfully utilised again in 2008 reducing amount of virgin aggregate used, landfill tax and fuel costs.

Added Value by BBIS Completed • Appointed Recycling Manager • Set up recycling centres as individual operations • Engaged supply chain • Measure recycled content of excavations • Built up knowledge and experience from BBIS group • Identifying market leading initiatives • Reduced the quantity of excavated material subject to landfill tax • Increased the quantity of recycled material being re-used • Partial recycling of gully waste The Future • Trial “Re Heat” asphalt • Detailed feasibility study of owning part of the supply chain • Measure the recycled content of all key products purchased • Continue engaging supply chain • Continue building knowledge and experience of sustainability • Potential mobile recycling of all gully waste.

Sustainability Update

h. NY Sustainability Cement Stabilised Pavements Area 6 Area 7 Area 2 B 6451 Menwith Hill B 1222 Newthorpe A 19 Thircon R/B to Mile House 660 m 2 7, 000 m 2 2, 300 m 2 ______ Total 9, 960 m 2 This in-situ recycling process has reduced potential h. NY tipping by approximately 21, 900 tonnes. With a standard fleet of 10 t lorries this equates to 2, 190 loads. Assuming an average journey of 12 km per load one way, transport time and fuel is reduced by 52, 560 lorry kilometres.

h. NY Sustainability Recycled Road Planings • 1, 300 tonnes of road planings have been utilised in Area 6 at Little Ouseburn and Area 4 at Sands Lane, Wintringham, as sub-base. • This equates to a reduction of approximately 7, 800 lorry kilometres. • A saving of 1, 300 tonnes of virgin aggregate is also achieved. Dry Stone Aggregates • To date 2, 000 tonnes Type 1 at Towton and 350 tonnes Type 1 at Whitewall Quarry have been recycled, saving the import of 2, 350 tonnes of virgin rock. • It is now our intention to monitor sustainability savings in transport.
